IMPROVED GAS-MACHINE.

The Schedule referred to in these Letters Patent and making part: of the same.

in the county of Jackson, andState of Missouri, have invented a new and improvedPneumatic GasMachine, for the manufacture of gas from gasoline, or the lighter products of petroleum; and I hereby declare that the following is a full, clear, and exact description thereof',

reference being had tothe accompanying drawings,

and to the letters of reference marked thereon.

My invention consists in the constructionof a gasmachine which shall be cheaper and more simple than those heretofore in use, and thus tocheapen the pro-V duction of gas, for, in one device, I combine a blower and an evaporator.

` To enable others skilled in the art to make and. use

my invention, I will proceed to describe its construction and operation. o

Figure 1, in the drawings, represents a vertical longitudinal section of the machine, and

Figure 2, a vertical cross-section of the same, taken through the line ff.

The lines A A A A represent the form and walls of a reservoir or vessel to contain the gasoline to be used in operating the machine; and this should be made of any suitable metal, and water and air-tight.

N is an inlet-pipe, by which the gasoline is intr0- duced, and

O, a connecting-pipe, for the discharge of the gas as it is formed.

The letters B represent the outer case or shell of a revolving cylinder or drum, and

The letters C, the inner case or shell of the same.

The letters I) indicate metallic partitions, which run around spirally between the inner and outer cases or shells of the cylinder' B, and divide the intervening space into a corresponding number of compartments or grooves, like internal screw-threads. V

The inner and` outer casesand the partitions, are made fast together, and water and air-tight, with the exception of the proper openings, which will be 'de- V is firmly made fast to it; and the hollow in the sleeve opens into the interior of the cylinder.

The rear end of the inner space of the cylinder is tightly closed, while the other end is left open into the body of the cylinder.

This cylinder revolves upon a hollow shaft, E, which Vpasses through the sleeve, which is in the centre of the front head ofthe cylinder, and thence through the centre of the rear head of the same, and then is fastened into the rear end of the large vessel, so as to be stationary in it, ,the end of the shaft being closed airti ht.

vgIn order to make an air-tight joint where the hollow shaft passes through the rear head of the cylinder, a washer, a, may b made fast on the hollow shaft, and another, b, likewise fast on the inner side of the head, as a bearing for that end of the cylinder; another, c, on the outside, by which' the head may be held against the washer a, by means of the spiral spring K.

In revolving, the cylinder, by its sleeve I, forms a journal in the stuing-box L, on the front end of the main vessel.

The hollow shaft E never revolves, and the pipes H and G, which are closely jointed into it, forming a siphon, the use of which will be hereinafter explained.

The hollow shaft E is open at the end, m, for the air, which passes along in it until it comes to the closed partition p, and then passes up the pipes F, and thence into the interior of the revolving cylinder.

The joint between the end, m, of the sleeve I and the hollow shaft E, is made air and water-tight by the stuiiing-box M.

One-third, or less, of the length of th spiral compartments, marked d, should be loosely lled, at their rear or discharge-ends, with cotton,`wool, or other fibrous and porous material, which is to perform the oliice of thoroughly subdviding the gasoline or other efluid used, in order that the air may be the better enabled to absorb its vapors.

The hollow shaft E should pass through the outer main vessel so much below its centre that the cylinder may approach very near its. bottom, for two reasons: rst, that the machine may make gas when only a small quantity of the gasoline is in the vessel; and, secondly, that there be room in the upper'part of the vessel for a sort of reservoir for the naphthalized air discharged from the spiral compartments or worms; and I will add, that these compartments maybe made irregular in form, so as tobe much larger midway be tween the points of eutranceand exit, and in that way their eiiiciency may be increased; or, the space between the inner and outer shells of the cylinder-may be filled with metal tubes or pipes bent in the spiral form.

The cotton or other fibrous material in the exit-ends of the grooves may be held om discharge by small stays, h h h h.

When the machine is in operation, the cylinder should be iilled with gasoline up at least as high as the bottom of the interior space, but not higher than the top of it.

The cylinder may be revolved by means of a weight or spring, or any suitable attachment to the sleeve I.

The operation of the machine is substantially as follows:

A proper quantity of gasoline having been introduced into the cylinder, and the air admitted through the mouth of the hollow shaft E at m, lls all the space in the interior which has not been filled with gasoline.' The cylinder is then revolved. Each groove beingilled with air, takes in a quantity of the fluid, which is driven around its circuit, the air being driven before it, and out at the exits, and then out at O, and the fluid, after being discharged, falling uponthebottom ofthe outer vessel. The Huid, being thus constantly discharged into the outer vessel, induces a pressure, which causes thev duid to rise in vpipe H, thence into the hollow shaft E, and thence it flows down through the pipeG, and is discharged into the cylinder from whence it started, thus keepingy it, hy this Siphon-like action,

.always lled; and the pressure vis increased by theV constant discharge of air also into the large vessels.

It will be observed `that the operation of my machine eiects avery thorough subdivision and exposure Y of the duid to the air, and this affords the latter great facility in takingy up andI absorbing the combustible vapors of the gasoline or other duid.

At every revolution of the cylinder, the vwalls of the apertures or grooves are coated with the iiuid, and the cotton, wool, or other fibrous materiahthoroughly saturated with it, and then follows the air, to takel up its vapors. Q f

Thecylinder is revolved very slowly, so that there is but little wear and tear, ory strain, upon the parts,

.and the machine is always ready for use, and the manufacture of gas by it is very cheap, while the light a'orded by'it is as good as or better than that afforded bythe common coal-gas.
